- IAEA chief Rafael Grossi signaled on June 24, 2026 that his inspectors will visit Iranian nuclear enrichment sites, calling it the firmest commitment yet from the UN agency blocked by Tehran since Israel's 2025 12-day war on Iran.
- Grossi cited a Memorandum of Understanding signed by both presidents that 'explicitly states that the nuclear activities… will be supervised by the IAEA — in all letters,' and said the timing of inspections is 'important, but not essential.'
- Iran is believed to store enough highly enriched uranium for as many as 10 nuclear weapons, and is the only country in the world to enrich uranium up to 60% purity without a weapons program, according to the report.
- The US and Iran offered contradictory remarks on June 23, 2026 about whether the sites would be inspected, a day before Grossi's statement.
- The interim deal calls for Iran's uranium stockpile to be 'downblended' from highly enriched levels, with IAEA verification central to that process.
- Grossi made the remarks at a news conference at the tsunami-hit Fukushima Daiichi nuclear power plant in Japan, not in Tokyo as initially reported.
Why it matters: IAEA verification is the concrete enforcement mechanism of the US-Iran deal — without access to enrichment sites, there is no way to confirm Iran actually downblends its 60%-enriched uranium stockpile, which Western estimates say could yield up to 10 weapons. The contradictory US-Iran signals from June 23 suggest Tehran is hedging on the access its own president signed away, meaning Grossi's public invocation of the memorandum is likely aimed at pressuring compliance.
